[Jacopo Mondi <jacopo.mondi@ideasonboard.com>]

Add the bindings documentation for Omnivision OV5670 image sensor.

Signed-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com>

v6->6.1
- Use additionalProperties: false for endpoint properties from
  video-interfaces.yaml
- List 'remote-endpoint' among the accepted endpoint properties
  now that we use additionalProperties: false

+description: |-
+  The OV5670 is a 5 Megapixels raw image sensor which provides images in 10-bits
+  RAW BGGR Bayer format on a 2 data lanes MIPI CSI-2 serial interface and is
+  controlled through an I2C compatible control bus.
